topsoil underlain by sandy lean clay glacial till soiLs to the termination depth of the <br /> borings. <br /> Penetration resistance values(N-Values),shown as blows per foot(bp�on the boring logs, <br /> within the silty sand soils ranged from 11 to 21 bpf and within the sandy lean clay soiLs <br /> ranged from 5 to 17 bpf. The N-Values indicate the soils are generally in a medium dense <br /> density of inedium to stiff consistency with some upper soft zones. <br /> 3.2 Groundwater <br /> Groundwater was not encountered in borings while drilling or to cave-in depths of 11 to <br /> 13 feet after removing the auger from the boreholes. However,given the cohesive naiure <br /> of portions of the soils, it is possible that insufficient time was available tor perched <br /> groundwater to seep into the borings and rise to its hydrostatic level. <br /> Groundwater measurements were made as noted and shown on the boring logs. <br /> Groundwater monitoring wells or piezometers would be required to more accurately <br /> determine water leveLs. Seasonal and annual fluctuations in the groundwater levels <br /> should be expected. <br /> 3.3 Laboratory Tests <br /> Laboratory moisture content tests were performed on selected samples recovered from the <br /> soil borings. Table 1 below summarizes the results of the laboratory tests. Results of the <br /> laboratory moisture content tests are shown on the boring logs adjacent to the sample <br /> tested. <br /> Table 1.
